Developing matching heuristics and integrating with AMW
The AMW plug-in provides a set of matching transformations that automatically create weaving models. However, it may be necessary to develop new transformations, due to several reasons: to develop new heuristic methods; to better tune the existing heuristics; or to execute several transformations at the same time and with different weights.The AMW plug-in provides an extension point that enables to easily plug new matching transformations. This page explains how to contribute to this extension point. This is a technical document that requires previous knowledge about development of Eclipse plug-ins.
create OUT : AMW from IN : AMW, left : MOF, right : MOF;- HOT; the higher-order transformations are added in the menu "Transform". The higher-order transformations produce an ATL transformation model. This model is used to transform the models conforming to the left metamodel into models conforming to the right metamodel.
create OUT : ATL from IN : AMW, left: MOF, right: MOF;The developer must indicate the transformation file ('.asm'). The weaving model opened in the weaving panel is the input weaving model.
